John Stuart Bell: recollections of a great scientist and a great man

This contribution to the book in honour of J.S. Bell will probably differ from the remaining ones, in particular since only a part of it will be devoted to specific technical arguments. In fact I have considered appropriate to share with the community of physicists interested in the foundational problems of our best theory the repeated interactions I had with… Read more →

Non-reflexive Logical Foundation for Quantum Mechanics Latest Results for Foundations of Physics on 2014-11-02 12:00am GMT Abstract On the one hand, non-reflexive logics are logics in which the principle of identity does not hold in general. On the other hand, quantum mechanics has difficulties regarding the interpretation of ‘particles’ and their identity, also known in the literature as ‘the problem… Read more →

Quantum Phenomena Modeled by Interactions between Many Classical Worlds

Michael J. W. Hall, Dirk-André Deckert, and Howard M. Wiseman, Quantum phenomena modelled by interactions between many classical worlds. Phys. Rev. X 4 041013 [17 pages] (2014). At the request of Dr Shan Gao, I’m posting here a short discussion of this new paper. This work is motivated by the quantum measurement problem, which suggests that orthodox quantum mechanics does not… Read more →

Haag’s theorem: proposed resolution

I’m in the process of drafting a paper on resolving the problems associated with Haag’s theorem: Haag, R. (1955). “On quantum field theories,” Matematisk-fysiske Meddelelser, 29, 12. This involves resurrecting direct-action theories as a possible account of how Nature really works. It is perhaps not well known that John Wheeler himself was attempting to resurrect the direct action approach in… Read more →
